. Application filed March 18; 1929. Serial No. 347,864.

This-inventionrelates to new and useful improvements 111 storage batteryterminal pullers.

, It is the principal object of my invention 7 to provide forapplication to a corroded or other tight storage battery terminal, ascrew ca I device by which it may beeasily removed.

The subject of this application d-ifiers from the terminal pullerdisclosed in my prior application Serial Number 26%,812 now Patent No.1,707,379, by being of more universal application. 1 I In theaccompanyingdrawing illustrating my invention, Figure 1 a top plan viewof my terminal puller applied to a late type of storage batter'y'terminal.- Figure 2 is a side view thereof. 'Figure 3 is an end viewof the same. Figured is' a sectional view taken through the device onthe line ll r of Fi ure 1., Ficiu'ree is a bottom lan View of'mypullerapplied to a diiferent type of terminal than that disclosed in thepreceding figures. And Figure 6 is a top view of the assembled castingand win s, omitting the top plate, pressure-screw and hooks.

Referring to the accompanying drawing for a detailed descriptionof theform of embodiment of my invention therein, the numerall designates acasting which is Hshaped in side view and has a cross portion 2 with awide central part. Secured by screws 3, 3 to thetops of the legs of theH casting 1 is a cap plate 4: formed with a top rib 5 having a centralscrew hole which extends downwardly through the plate.

Mounted between the cap plate 4 and the middle part of the cross portion2 and abutting against a hollow axial projection 6 on the latter, aretwo wing members 7, 7. wing member is formed with a tapering hole 8which is of greatest diameterat the bottom to freely receive a swivelhook 9 having its upper end threaded; To the threaded end of each hook 9a knurled cap nut 10 is applied. At its outer upper end each wing 7 isformed with a beveled crown portion adapted to engage the cap plate 4and whose top surface is in the same horizontal plane disclosed Eachasthe top of the plate for, an even engage- 'ment by a respective cap nut10.

Each Wing 7 is formed with an end pro- JGCblOIl 7 which is received byan arcuate;

groove in the inner surface of the cap plate i t. Thispermitsthe wing tobe easily shift ed about theconical projecti'on'G, which acts as rearstop for it, to a position where the ho0k9 carried by the wing may bestengage the terminal to be removed. ment of the projections 7 on theinner ends of the wings 7, in'the arcuate grooves of the cap plate 4:,prevents these wings from being pulled out when the cap nuts 10 arescrewed down on them; (See Figure l).

'Formed in the centra-l ribbed portion of the cap plate 4 is a screwhole which is directly .over a similar hole which extends -"through thecross port1on 2- of the 'castlng 1. I

Contained 1n the screw holes ust referred to, is a screw or stud 11formed with an outer wrench receiving head 12. On its'inner end gage apost 14: of a storage battery 15.

" Near its lower end'each leg of the H cast- The engagethe screw 11'carriesa swivel cap 13 to engaging. from the sides a terminal such asthat shown in Figure 5, the studs 16, 16 assist one of the hooks 9 inestablishing a firmgrip on the terminal when the latter is to be pulledfrom a post I l. 1 7

Preparation for the pulling-0f a terminal such as that shown in Figures1 to4 inclusive, is made by fittingthe central hole in the cross portion2 of the casting 1 over the battery post 14 upon which'this terminal,

which will be designated by the numeral 17,

has corroded; The hooks 9, 9 are then drawn tightly into engagement withthe cable receiving and clamping portions of the terminal by the capnuts 10, as'shown in Figure 2, and the'studs 16, 16 screwed into engage-.ment with its middle portion. The screw 11 is then turned to engage thetop of the post, whereupon the casting 1 will be elevated'by the screwto pull the terminal from the post through the instrumentality of thehooks 9 and studs 16.

i If a terminal such as that shown in Figure q 5 is to be pulled, thecasting 1 is placed over its post 14 as before described. The studs 16,16 are then screwed against the terminal, which will be designated 18,and one of the hooks 9 applied to the clamping portion of the latter.The hook 9 is then drawn into tight engagement with the terminal by thecap nutlO. lVhen the screw 11 is then turned against the post 14, theterminal 18 will be pulled from it with ease by one of the hooks 9 andboth of the studs 16.

It will thus be seen that my improved terminal puller may be applied toterminals of the latest ypes to remove them with ease from the posts ofthe storage batteries receiving them.

Having described my invention, I claim:

1. A device of the type described for pulling a terminal from astorage'battery post, comprising a screw holding member, a top on saidmember formed with arcuate grooves in its inner surface, said screwholding memher and top being formed with oppositely disposed screwholes, a screw in said holes adapted to engage said post, wing membershaving inner ends shaped to travel in said grooves, and means carried bysaid wing members for removably engaging said terminal to pull it fromthe post when the pressure of the screw is applied to the latter.

2. A device of thetype described for pullinga terminal from a storagebattery post, comprising a screw holding member, a top on said memberformed with arcuate grooves in its inner surface, said screw holdinmember and top being formed with oppositely, disposed screw holes, ascrew in said holes adapted to engage said post, wing members havinginner ends shaped to travel in said grooves, a

hollow axial projection on the screw holding member through which thescrew passes and which is engaged by the rear ends of the wing membersin any of their adjusted positions,

and means carried by said wing members for removably engaging saidterminal to pull it from the post when the pressure of the screw isapplied to the latter.

3. A device of the type described for pulling a terminalfrom a storagebattery post, comprising a screw holding member formed with a centralscrew hole, a screw in said hole adapted to engage said post, legs onsaid member adapted to straddle said terminal, and studs passing throughsaid legs for engagement with said terminal to pull it from the postwhen the pressure of the screw is applied to the latter.

. 4:. A device of the type described for pulling a terminal from astorage battery post, comprising a screw holding member formed with acentral screw hole, a screw in said hole adapted to engage said post,legs on said member adapted to-straddle said termlnal, a hook swiveledto said casting for removable engagement with said terminal, and studspassing through said legs for engagement with said terminal to assistthe hook in pulling it from the post when the pressure of the screw isapplied to the latter.

5. A device of the type described for pulling a terminal from a' storagebattery post,

comprising an H shaped casting, a top plate on the latter formed with acentral screw members for removable engagement with said terminal, andstuds passing through the lower ends of the leg portions of the H shapedcasting for engagement with said terminal for the purpose specified;

6. A device of the type described for pu1ling a terminal from a storagebattery post, comprising a screw" holding member formed with a centralscrew hole, ascrew insaid hole adapted to engage 'sa-id post, shiftablewing members projecting. from the sides of the screw holding member,arcuate guiding and holding means on the screw holding member for thewings, arcuate means on the wings cooperating with said guiding andholding means, and hooks carried by said wing mem bers for removablyengaging said terminal to pull it from the 'post when the pressure ofthe screw is applied to the latter. 7

In witness whereof I have hereunto set my hand this 16 dayof March,1929.
